The tii has sat for 12+ years - now what?

The present Owner says he drove the car into his garage some 12 years ago and that the previous owner (German) had 'rebuilt' the engine less than a 1000 miles previously.

I am not banking on anything - in fact I haven't even attempted to turn the engine from the crank pulley because I don't want to scuff the cylinder walls or snap a crusty frozen ring, etc.

Should I do a marvel mystery oil pour thru the plug holes and then try?

If the compression is OK I'd just as soon leave things as they are, do an oil change and then hook up the motor and see what compression I have.

There is also a question about whatever the hell in in the fuel system and what to do about the pump before I try to turn it over. I don't want to start it - just test compression but the pump is lubricated internally by oil and will have been drained empty - is there a
way to add oil to it before turning?
